BA series pumps

6 Pump – general
6.1 Preparation for starting the pump or pump unit
If the pump is equipped with a vacuum pump, the pump does not have to be filled with the pumped
liquid.
If there is no vacuum pump present, the pump must be completely filled with the pumped liquid.
1. Make sure that a non-return valve is installed in the
suction pipe.
2. Open the cover on the top of the pump.
3. Completely fill the pump with the pumped liquid.
4. Close the cover.
Note
Filling the pump simultaneously purges the air from the pump.
On a BA dry-prime pump, there must be as little back pressure in the pressure pipe as possible while
purging air from the suction pipe (‘priming’) and until the pump begins to pump liquid. This allows the air
in the pump unit to be purged more quickly.
